Résumé

Specimens of Pomatoschistus canestrinii (Ninni, 1883) were collected from 2000 to 2002 along the eastern Adriatic coast. The morphology of 64 specimens from 11 locations was examined. High variabilities of important morphological characters, including body squamation, number of transverse rows of sensory papillae suborbital row a, and head canal development, were described. The present findings, contradictory to valid species diagnosis and genus diagnosis, extend species taxonomical delimitation. Additional data on ecology and geographical distribution of the eastern Adriatic specimens are provided.
